  • 摘要: 针对太湖三山岛农村生活污水分布面广而分散和水质水量不稳定，以及三级处理费用高等问题，提出了人工湿地组合工艺。以设计规模为1 000 m3/d、处理生活污水的工艺系统为对象，探讨了氮元素在系统中的去除效果、途径及其一级去除速率常数。结果表明，该工艺对NH4+-N去除效果较好，出水NH4+-N平均达到地表水Ⅲ类，TN平均接近地表水Ⅴ类；潜流人工湿地、好氧生态塘C、兼性生态塘A和表流人工湿地D对氮的去除量分别占组合工艺去除总量的52.05%、18.65%、16.65%和12.65%；组合工艺对NH4+-N和TN的平均一级去除速率常数分比别为（14.47±2.01）和（25.91±4.99）m/a。
    Abstract: To solve the problems of quality and quantity instability of decentralized rural domestic sewage in Sanshan island,Taihu lake,as well as the high cost of tertiary treatment,we put forward a combined constructed wetland process.The system with design capacity of 1000 m3/d was studied,for treating domestic sewage.The removal effect,removal pathway and first removal rate constant of nitrogen in the whole system were also explored.The results showed that this combined process performed well on NH4+-N.The effluent NH4+-N could meet grade Ⅲ averagely according to the China environmental quality standards for surface water; the effluent TN approached grade V.The partial N removal amounts in subsurface flow constructed wetland,aerobic ecological pond C,facultative pond A and surface flow constructed wetland D made up 52.05 %,18.65 %,16.65 % and 12.65 % of total N removal by the combined process.The average first removal rate constants for TN and NH4+-N were (14.47±2.01) and (25.91±4.99) m/a,respectively.
